A 100mW Dual-Band CMOS Mobile-TV Tuner IC for T-DMB/DAB and ISDB-T

Abstract

A 0.18μm CMOS dual-band low-IF mobile-TV tuner IC for T-DMB/DAB that supports Band-III and L-band is presented. By modifying a few metals and via masks, the IC can support VHF and UHF bands for ISDB-T partial reception. The chip meets all the specifications of both applications with a sensitivity of <-98dBm while consuming 100 mW from a 1.8V supply and occupying 3.4 X 3.3mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup>
